Question

why is the change in Ph levels important in the alimentary canal ?

Answer 1

Our stomach produces HCl. It helps in digestion of food without harming the stomach.

During indigestion, the stomach produces too much acid and this causes pain and irritation.

To get rid of this pain, people use bases called antacids.

These antacids neutralize the excess acid in stomach.

Magnesium hydroxide (milk of magnesia), a mild base is often used for this purpose.
